To all 'whom it may concern:

e it known that I, ERNST AUGUST KROENKE, a citizen of the United States, re sidin in New York, .borough of Brooklyn, and tate of New York, have invented certain new and useful Improvements in Refrigerators, of which the ollowing is a speciication.

This invention relates to im rovements in refrigerators and more especia ly to refrigerators which are intended for the use of groccrs and liquor dealers, for storing different articles in a number of compartments, and in which they are stored in such a manner that quick, convenient and easy access in each com artment is obtained; and for this purpose t e invention consists of a refrivaround an upright center ost attached to a suitable latform, the re rigcrator being of polygon shape and provi ed with an icechamber in the u per art, storage-chambers around the ice-c am er, dri ans for the ice water below the bottom oft e ice-chamber, additional stor oe-chambers arranged around the drip-cham er, the storage chambers being provided with sliding outer doors and slidinginner doors connected therewith so as to open the opening of the dri -chamber When the sliding doors are close and a provision-chamber 1n the lowerpart of the refrigerator. n l

The invention consists of additional dedescribed hereinafter and finally pointed out in' the claims.

In the accompanying drawings, Figure 1 represents a vertical section of my improved re rigerator, Fig. '2 is a plan view partly in horizontal section on line22 Fig. 1, and. Fi 3 is a section on line 3 3 on Fig. 1.

imilar letters of reference indicate 'the same parts in the different iigures of the drawings. l i i Referring to the drawings, a represents aA suitable platform which is permanently attached to the floor. In the center of the platform a, is attached an upright post or column t, preferabl made of cast-steel. By means of anti-fractional bearings, a refriger- R of c lindrical or olygonalsha e and o suitab e height, wlliich 1s provide at its center with a sheet metal tube t can rotate freely on the .platform post, so as to give access Specification ofLetters Patent.

chamber i, is arranged at the u per central part of the refrigerator, it b through openings which are closed by means of hinged doors G, the compartments adjacent the ice-chamber being like-wise closed by means of hinged doors G1. On both sides of the ice-chamber and the char ing compartments are arranged additionz storage- /chambers C which connect by openings at the innerends with the ice-chamber and are eing filled closed by outer hinged doors. These stor- I age chambers are used for storing milk, wines and similar articles. v

Below the slotted bottom B of the icechamber, is arranged a 'drip-chamber D in which are located inclined shelves d, and an annular trough d1, which is arranged around the central sleeve inclosing the center post and from which the drip-water is conducted by means of a dri -tube d2 to the bottom of the refrigerator W ere a receptacle Z3 is provided. l i

The ice water which drops through the slotted bottom of the ice-chamber cools the delivery shelves as well as the trough, and thereby the air ascending from the lower or provision-chamber is cooled and keeps the refrigerator at a low temperature. This air, which ascends from the lower provisionchamber, passes upwardly into the dripchamber D and then into the ice-chamber. f Around the drip-chamber D are arranged compartments C1 which are closed by means of sliding doors F, that are guided in ways of sliding doors F are connected by inclined bracket rods f with interior. doors F1 which 'move over the openings in the walls of the drip-chamber when the doors F are raised for giving access to the compartments C1 and which are lowered when the doors F are moved to close the compartments. The bracket-rods f are arranged on both sides of the sliding-doors in such a manner as to conneet the lower part of the same with the upper parts of the inner doors F1 so that bracketrods f do not interfere with the tubs of butter or other articles stored in the compartments C1. The connection between the outer doors and the inner doors has the advantage that when the charge-doors are o ened, the su ply of cold air from the drip-chamber into t e compartments C1 is shut ofi', while when the outer doors are closed, the supply of cold air to the compartments C1 is restored, and thereby these compartments retained at a t erein.

lby dotted lines in Fig. 2, so as to light up the frigerator are provided with colored glass .ticles and the replacing of the same with a chamber to the outside is prevented by means of the sliding doors arranged in connection with the middle compartments.

Having thus described my invention, I claim as new and desire to secure by Letters Patent.

1. In a refrigerator, the combination of a casing having a central ice-chamber located in the upper part thereof, walls defining storage-chambers arranged around said icechamber, walls dividing the middle part of said casing into a drip-chamber below said ice-chamber and compartments surrounding said drip-chamber, there being openings in the exterior walls of said compartments and in the walls of said drip-chamber, doors to close the openings of the compartments, doors to close the openings of the drip-chamber, means for connecting said doors so that one is opened when the other is closed, and a wall orV partit-ion which divides said compartments from the lower part of the casing and forms a provision chamber below the drip-chamber and said compartments.

2.' In a refrigerator, the combination of a casing having an ice-chamber at the upper part, upright walls dividing the middle part of said casing into a drip-chamber below said ice-chamber, and compartments surrounding saidv drip chamber, the walls of said dripchamber and the exterior walls 0f said compartments being provided with openings, sliding doors movable over said openings of the drip-chamber and compartments, and means for connecting the doors of the compartments with the doors of the drip-chamber, whereby the corresponding door of the drip-chamber is closed when each compartment door is opened, and vice versa.

In testimony, that I claim the foregoing as my invention, have signed my name in presence of two subscribing witnesses.

lower temperature notwithstanding the fact l that they are subject to being frequently] o ened to give access to articles storediI The lower compartment C2 under the dripchamber, which compartment is divided off from the vcompartments C1 by a horizontal wall or partition J, is used as a provision i chamber for storing articles or butter tubs, so i as to have them ready for use when the butter in the tubs placed in the compartments E C1 is sold. The provision-chamber may, of course, be used also for the storing of other ar ticles. I The chamber is provided with hinged doors H along its sides'so as to give access to all parts of the chamber. The annular' space between the compartments may be used for arranging electric lights in same, as indicated part of the refrigerator from which things are to be taken, by simply pressing a switch in the outer side of the refrigerator. The panels that are formed inthe frame of the repanes so as to throw the light of the incandescent lights to the outside. If desired, all lights may be kept burning so that the refrigerator can be rotated for moving the articles from the different compartments, the lighted up interior facilitating the removal of the arnew supply. The exterior walls of the refrigerator are made double and filled with non-conductor of heat as is customary in con struction of refrigerators.

The advantage of my improved rotatable refrigerator is that any of the compartments are accessible from a certain point without having to run around the refrigerator, as the same can be-readily turned by the attendant to bring an desired part of the refrigerator within reac i.v By a central arrangement of the ice-chamber and drip-chamber, the cold air is distributed to all the chambers and compartments of the refrigerators so as to establish a uniform temperature therein, and the escape of the cold air from the drip-
